Don’t get me wrong, I love tuna as much as anyone. I love it on a plate of sushi, in a casserole, I love it grilled, seared, in a ceviche, on a burger bun. A piece of tuna in front of me, in any form, has a very low life expectancy.

But I worry, at night, about how much tuna I’ll be able to eat in the future. Because according to scientists, tuna are in trouble. Hardest hit is the Atlantic Bluefin Tuna; stocks are down 75% in just the past couple of decades. We (and I mean all of us, internationally) are eating these fish faster than they can reproduce and grow.

It’s a short-term vs. long-term question. Yes, restricting trade would hit some country’s economies, with varying degrees of severity, in the short term (and this hit would likely be permanent, forcing those economies to adapt and adjust.)

But allowing the tuna trade to continue apace may mean the end of the Atlantic Bluefin altogether. Which, of course, also means the end of the profits it generates. Permanently. When it’s gone, it’s gone.
